The main use case for the NC (for me) would be a backup for my QC, which I currently have set up to send a pre-IR signal out of one output and a post-IR signal from the others.
If the NC could be set to send the Post-IR signal from one output, and a Pre-IR signal from the other, this would serve as a great backup unit for those using IRs with a real cab on stage.
This would (ideally) just be a configuration option that would apply to all presets and is switchable from a main menu.
